Application filed May 1908. Serial No. 436,144.

To aZZ whom it mag; concern Be it known that I, CHARLES rlnnennfr ,DRAPEIQ a citizen of the United States of America, and a resident of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful linproveinents in Metallic Receptacles, of which the following is a specification.

My invention relates to improvements in metallic` receptacles, such as barrels or drums, and has for its object the provision of a containing vessel which shall be strong and durable for withstanding hard usage, and present liquid tight joints.

My improvements are more commonly utilized in the construction of metallic bar-r, rels which are adapted to 'contain any solid or liquid articles of commerce not likely to attack the metal. Accordingly, itl .is highly desirable that the necessary joints shall be liquid-proof, and so constructed as to avoid injury thereto causing leakage, under conditions of hard service.

Briey referring to the features of construction about to be explained, l say that a receptacle constructed in accordance with my invention comprises a body portion, which may be formed of suitable .tubular lengths of seamless or jointed sheet metal. The ends or closures thereof'are formed of closely tting heads or disks having upwardly and outwardly turned edges'or lips, which with the extreme edges of the cylindrical body portion, are bent over to forni a double locked joint. nteriorly of the annular joint thus formed, is positioned arigidinetal ring, preferably channeled t receive said double locked joint, and over the lower edge of the channel, the adjacent portions of the doubled inetal are bent to loch said ring in place, and forni a chime or supporting edge for the barrel or receptacle.

The details of this construction may hes-t be gathered from the' annexed drawings, wherein Figure is a view in side elevation partially broken away, of a barrel constructed in accordance with my invention. Fig. il is an enlarged cross-sectional view showing in detail the preferred double locked .L joint within the channeled ringa F 1g. lll 1s a fragment partially broken away, showing the body of the receptacle. lV is Specicaton of Letters Patent.

'cross-sectional 'view of the channeled ring.

Fig. V is a cross-sectional view of the metallic head. Fig. VI is a fragmentary detail also in cross-section, illustrating the double locked joint before it is forced within 'the channel or recess; and F ig. Vil is a fragmentary cross-sectional view of the double locked joint in association With a slightly modified channeled ring.

Throughout the several figures of the drawines .l have employed the same character of reference to indicate similar parts.

lt will be understood that the metallic receptacle herein shown is typical merely of the .structural features of barrels or containing' drums for any purpose whatsoever; some being successfully1 employed for the snipnient of such commodities as keroseneor gasolene by reason of their tight jointsV which avoid material leakage or evaporation. llhese joints herein specifically set forth, are characterized by a closure comprising' a doublelocked joint or annular seam respectively, preferably compressed forcibly within a channeled'ring substantially 'i3-shaped in cross-section and of somewhat lessV minimum diameter externally', than the-normal inner diameter of the receptacle.

r)The body portion a preferably' is formed of cylindrical sheet metal, wherein the heads or closure parts h are adapted closely to fit. These closure parts ordinarily comprise a convex disk surrounded by an upturned rim Z" and an outwardly turned flange b2, which member being inserted within: the cylindrical body portion, the adjacent edges or flanged rims a b2 are bent about each other,

as best .shown in initial forni in Fig. Vl to form a double locked seam or joint. The channeled ring c is then inserted within the recessed head, as shown, and the annular joint of the barrel-head is forced within the channel, tightly compressing the' same, and closely drawing the metal faces a2 b3 over the lower edge of the channeled ring,.as best shown in F 1g. Il. By this means, not only are the advantages of a double locked joint attained, but the chime is given approximately a unitary construction, and strengthened to any necessary or desired extent by the heavy body of the channeled ring. As thus formed, the barrel is provided` with a heavy chime sufficient for withstanding all edges or double locked joint.

Although the preferred construction is exhibited in Fig. ll, the channeled ring c dges not necessarily extend over or beyond tli'e'double locked joint, particularly when the receptacle is adaptedior less severe service. For this construction, a modification, suoli as shown in Fig. VH, may be at tipted, wherein the channeled ring is subst ntially iiush with the outer portion oli/the double `locked joint, and the channel pr er is approximately of an irregular, ulnequal Q- shape, v

Having now described `a receptacle or receptacles embodying my invention, I claim as new and desire to secure by Letters Patent, the ollojwingzl. ln' a metallic receptacle, the combination with a body portion, of a head or closure part fitting therein, provided with up turned edges lying adjacent to the edges of the body portion, and bent over the saine to f form substantially a double locked joint,

and an interiorly positioned channeled meinber substantially C-shaped in cross-section over the lower edge of which. said double locked joint is bent to tighten and strengthen the saine, substantially as set forth.

2. ln a metallic receptacle, the combination with a cylindrical body portion formed of sheet metal, a disk-like metallic closure part inserted Within'the end of said body portion having upturned edges united with the edges oi: the body portion to form a sub,- stantially double locked joint, and a channeled ring substantially C-shaped in crosssection interiorly positioned within the head thus formed, wherein the double locked joint is compressed to form a supporting edge or chime, substantially as set forth.

3. In a metallic receptacle, the combination with a cylindrical body portion, of disk-like heads ci' closure parte provided nineties to form substantially integral chimes for i the receptacle, substantially as set forth.-

et. In a permanent closure for metallic receptacles, the combination with a substantially cylindrical body-portion ormed of sheet metal, of a disk-like metallic closure part, inserted within the end of said body-.

portion, having upturned edges united with the edges of the bodyportion to form an overlapped double-looked joint therewith, and laterally channeled metallic ring substantially S-shaped in cross-section interiorly positioned within the annular joint thus formed, wherein said joint is recessed to forni the chime, substantially as set forth.

5. ln a metallic receptacle, the combination with the cylindrical body portion, of a cupped closure part fitting closely. within the end thereof, and having an upturned lip extending beyond and turned over the edge of the body portion; the respective edges being again doubled over to form a tight joint,

and interior channeled ring substantially lf3-shaped in cross-section, but ofA less diameter than the body portion, annularly fitting within said cupped closure part, and extending beyond the joint, wherein the doubled edges are compressed for closing and strengthening the receptacle, substantially as set forth.
